The Lowdown
G’day, Rusty here. Let’s get straight into it. The next couple of weeks are a bit of a mixed bag for our stretch of coast, but there are definitely a couple of days you’ll want to clear from work.
The main event kicks off right away on Thursday morning, the 27th. We’ve got a solid 8ft of south swell rolling in with a 14-second period, and that’s pumping some serious energy into the water – we’re talking 2407 on the energy scale, which is proper strong. It’s a bit on the bigger side, so this one’s for the experienced crew, not the beginners. The wind is light and cross-offshore from the ENE, which is going to keep it clean. The water’s sitting at 72° which is pretty much spot on for this time of year. Thursday afternoon sees it drop slightly to 7ft, but the wind goes a bit more offshore, so it’s still going to be firing. This is the standout session.
Friday the 28th is a step down but still fun. Morning has 4ft of south swell, 12-second period, and a clean offshore breeze. It’s a much more manageable size, good for a wider range of surfers. The afternoon drops off quickly to 4ft and the wind swings a bit cross-off, so the magic fades a little.
The weekend is a bit of a flat spot. Saturday morning has a weak, short-period 5ft east swell, but it’s a bit jumbly. Sunday is pretty ordinary with small, weak waves. You’re probably better off doing other things.
Now, here’s the second highlight. Monday the 31st brings back some life. The morning has 7ft of east-northeast swell, with a moderate 8-second period. The wind is offshore and that’s going to groom it nicely. Good energy too, around 806. It won’t be as clean as Thursday but it’s a solid option.
We hit a bit of a lull from Tuesday the 1st of September through to Wednesday the 2nd. The wind goes onshore and cross-onshore, the swell gets messy, and it’s just not worth getting wet. The models are showing poor conditions, so don’t bother.
Things start to perk up again on Thursday the 3rd. The morning has 6ft of south swell with a nice 10-second period, and a light cross-offshore wind keeping it tidy. The afternoon builds to 7ft with the same period, and it’s still clean. This is another good window.
Friday the 4th sees a bigger 7ft south swell in the morning with a 12-second period, but the wind is howling offshore at 16 mph. It could be a bit blown-out and tricky. The afternoon drops to 5ft.
The second week is a bit more of a waiting game. Saturday the 5th and Sunday the 6th are smaller, but Sunday the 6th looks like a hidden gem. The morning is glassy, dead calm wind, with a clean 4ft south swell at 13 seconds. That’s a beautiful combination for a longboard or a fish. Monday the 7th is tiny, with 2ft of very long-period south swell at 16 seconds. That’s a very long-period groundswell, and it’s going to be breaking too straight for the beach breaks, but it might wrap into the points if you know where to look.
From Tuesday the 8th through to the end of the window on the 11th, it’s pretty quiet. Small swells, glassy mornings but not a lot of power. There is a pulse on Thursday the 10th with 4ft of south-east swell at 12 seconds and zero wind, which is glassy as a lake, so that could be worth a paddle.
So, to wrap it up: Thursday the 27th is your big, powerful day for the experienced surfer. Then Thursday the 3rd and Sunday the 6th are your other best bets for some clean, fun waves. The rest is a lot of waiting and watching.
Signing off.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
